Type of Research Project
- Basic science
What is the background of the project?
Protein phosphatase 2A (PP2A) is a central cardiac protein phosphatase that regulates a variety of cardiac processes including excitation-contraction coupling, Ca2+ handling, cell metabolism, myofilament regulation, and cell-cell communication. Moreover, current findings support the important role of protein phosphatases in both health and disease, for example by modulation of adrenergic signaling. Tight regulation of PP2A expression and activity is necessary to maintain its physiological function and aberrations in this regulation may contribute to cardiac pathophysiology. In this way, the role of cardiac microRNAs (miRNAs) appears as interesting objective to be investigated because they are small non-coding RNAs, which are involved in a wide range of biological processes by post-transcriptionally regulating the expression of protein-coding genes.
What is the aim of the project?
Identification of differentially expressed miRNAs in hearts of PP2A overexpressing mice and characterization of their role for PP2A-dependent signal transduction.
What techniques and methods are used?
- Isolating mouse cardiac cells and preparations for further examinations - Western blotting - RT PCR (reverse transcription polymerase chain reaction) and real time RT-PCR
